Overview

Coronary CT angiography (CCTA) can be helpful to diagnose the extent and severity of nonobstructive and obstructive CAD, as well as high-risk features of atherosclerotic plaque (positive remodeling, low attenuation plaque). Fractional flow reserve with CT (FFR-CT) provides additional information about ischemia related to lesion. Dosimetry is low for CCTA, with effective doses for most patients in the 3 to 5 mSv range.

CT scan


Favored use of Coronary CT Angiography (CCTA) Favored used of stress imaging
Aim Determining obstructive or non-obstructice CAD Managing ischemia
Likelihood of obstructive CAD Age<65 years Age≥ 65 years
Previous test Inconclusive prior functional study Inconclusive prior CCTA
Other indications Anomalous coronary arteries, evaluation of aorta, pulmonary arteries Evaluation of scar or microvascular dysfunction by PET or stress CMR





Pretest likelihood of CAD (coronary artery disease)
Low risk= Risk stratification of ASCVD (atherosclerotic cardiovascular disease), optional CAC (coronary artery calcium score)
Intermediate-high risk, younger patient <65 years, suspected less obstructive CAD = Favored Coronary CT Angiography
Intermediate-high risk, older patient≥ 65 years, suspected more obstructive CAD= Favored Stress Testing
The above table adopted from 2021 AHA/ACC/ASE Guideline[1]
